No trader can ever expect to be correct in every one of his market transactions. No individual, however well he may be grounded, no matter how much experience he has had in practical market operation, can expect to be infallible. There will always be mistakes, some unwise judgments, some erroneous moves, some losses. The extent to which such losses materialize, to which they are allowed to become serious, will almost invariably determine whether the individual is to be successful in his long-range investing activities or whether such accumulated losses are finally to wreck him on the shoals of mental despair and financial tragedy.
THE TRUE TEST
It is easy enough to manage those commitments which progress smoothly and successfully to one’s anticipated goal. The true test of market success comes when the future movement is not in line with anticipated developments, when the trader is just plain wrong in his calculations, and when his investment begins to show a loss instead of a profit. If such situations are not properly handled, if one or two losing positions are allowed to get out of control, then they can wipe out a score of successful profits and leave the individual with a huge loss on balance. It is just as important-nay, even more important-to know when to dessert a bad bargain, take one’s loss and count it a day, as it is to know when to close out a successful transaction which has brought profit.
LIMITS ARE A MUST
The staggering catastrophes which ruin investors, mentally, morally, and financially, are not contingent upon the difference between a 5 percent loss limit and a 20 percent loss limit. They stem from not having established any limit at all on the possible loss. Any experienced market operator can tell you that his greatest losses have been taken by those, probably rare, instances when he substituted stubbornness for loss limitation, when he bought more of a stock which was going down, instead of selling some of it to lighten his risk, when he allowed pride of personal opinion to replace conservative faith in the cold judgment of the market place.

It is common for traders to complain of a lack of confidence in their trading, but very often it is overconfidence that does them in. Overconfidence results from a lack of appreciation of the complexity of markets and an underestimation of the challenges of trading them successfully. In a sense, overconfident traders lack respect for the markets. They think that reading about a few setups or buying the newest software will prepare them to make money. Overconfident traders don’t want to work their way up the trading ladder: they resist the idea that screen time is the best teacher. They also chafe at the idea of growing their account. Rather than start with one contract and wait until they’re profitable before trading larger size, they want big positions—and profits—right away. Because they’re so eager to make money—and so sure they can make it—overconfident traders generally trade impulsively. They won’t wait for the setup to form; they’ll jump the gun—and get whipsawed in the process. Instead of being patient and waiting for short-term patterns to align with longer-term patterns, they will take every trade, enriching their brokers in the process. 
While much of these thoughts are outdated, it’s always a good idea to have a foundation of the first rules of speculation. Number 4 is dead on that you need to trade with money you don’t need and the patience to allow the trade to work out or not work. 
How do you personally get around from being “too early” or “too late” on an entry?
